Su Xiaoman makes a living by setting up a street stall and answering people's questions, but business is slow and she even gets caught up in disputes. At her lowest point, she rescues a stray dog named Da Huang from the rain and unexpectedly discovers that she can understand his thoughts. Da Huang is remarkably perceptive and can always expose the true intentions hidden behind people's words. With his warnings, Su Xiaoman becomes exceptionally good at reading people and understanding situations, gradually earning everyone's respect and putting an end to their contempt. She helps her uncle, who is drowning in debt, recognize the risks, sees through her cousin's pretentious facade, and gains a huge online following by sharing advice on understanding people and handling relationships. When she first meets the aloof Gu Beichen, a misunderstanding arises between them. Their constant bickering turns them into a pair of amusing rivals who gradually grow fond of each other.
